In recent years, daily hygiene and disease control issues have received increasing attention, especially the raging epidemics caused by the spread of deadly viruses. We focus on the construction of the interface of new polymer materials, which can provide a cyclic operation process for the killing and releasing of bacteria, and perform repeated regeneration, which is of great significance for the development of advanced medical biomaterials. In order to explore the basic physical phenomena of bacterial attachment and detachment on the polymer material interface by different amine groups, this study plans to synthesize four different butyl methacrylate (BMA)-based cationic copolymers with primary, ternary, and quaternary amine groups, and compare their effects on bactericidal efficiency. Since BMA can generate strong hydrophobic interactions with the benzene ring structure, this study used a polystyrene substrate to realize a self-assembled coated cationic copolymer interface for controlling the counterion-induced bacterial killing/release process. Furthermore, we introduced negatively charged ions to induce changes in the hydration capability of water molecules and control the subsequent bacterial detachment function. In this study, we propose possible directions to answer and clarify the above questions, and there is a basic reference principle that can lead to research work in related fields.
